3 days left!

9/6/15 – **Submissions to Manila are now closed. Please wait for results to be calculated.

We are anchoring in just under 72 hours.
If you’re still out there, now is the time to hurry!

I always send a confirmation email back to all entrants, so if you have entered and have yet to receive a reply – try resending your entry (after checking your spam inbox).
I’ve taken a peek at the current standings and the possibility of a tie-breaker is likely.
So after the deadline, try check your emails as there might be a tie-breaker to decide the winners.

Next time you’ll hear from me is the announcing of the winner of Manila!Until then.

Welcome!

What do crosswords in your newspaper, that numbered 9x9 grid that’s suddenly everywhere, the spot the differences on a cereal box, a chess position from some tournament match, the squiggles you see in common IQ tests and a high school mathematics exam have in common?

Answer: They can all be classified as a “puzzle”.
As a lifelong puzzler, I always find the word “puzzle” to be a bit broad. Everyone has their own definition of a puzzle. I imagine a certain place where all puzzle types gather and made known to everyone. That place would be Somewhere Over the Rainbow.
